I am currently working on a panel data with xtologit command. My data has a three-level structure where children are nested within mothers, and each child has several records over the years (panel data). I am wondering if I can use xtologit for this three-level model, or I can ONLY use meologit for this. I think xtologit can only be used for two-level data, but I am not sure. Thank you so much!
